Abstract

Lorsqu'une position de référence avant (Pf) est définie comme point d'intersection d'une ligne virtuelle avant (L1) et de la surface circonférentielle externe d'un noyau de rotor (31) dans une vue en plan, ladite ligne virtuelle avant (L1) passant à travers l'axe central (O) du noyau de rotor (31) et l'extrémité avant d'un aimant permanent (32) de chaque ensemble, et une position de référence arrière (Pr) est définie comme point d'intersection d'une ligne virtuelle arrière (L2) et de la surface circonférentielle externe du noyau de rotor (31) dans la vue en plan, ladite ligne virtuelle arrière (L2) passant à travers l'axe central (O) du noyau de rotor (31) et l'extrémité arrière de l'aimant permanent (32) de chaque ensemble, l'extrémité arrière (39) d'un pont avant (39f) est disposée à une position éloignée de la position de référence avant (Pf) dans la direction arrière (R) par un angle central autour de l'axe central (O) de ?a/24 (radian) à ?a/8 (radian), inclus, et l'extrémité avant (39r1) d'un pont arrière (39r) est disposée à une position éloignée de la position de référence arrière (Pr) dans la direction avant (F) par un angle central autour de l'axe central (O) de 0 (radian) à ?a/12 (radian), inclus. La ?a ci-dessus satisfait l'équation (1) suivante.?(1) : ?a = 2?/(Nfente)
